A collar 25 (Fig. is threaded on the" This invention relates to a flush-tank such as is commonly used in connection with toilets.

It is the general object of my invention to improve the construction of such tanks by providing improved valve mechanism so designed that the flush-tank will be more reliable in operation and more satisfactory for its intended purposes.

Particular features of the invention relate 'to the provision of an improved inlet valve and float-control therefor, and to the provision of an improved outlet valve particularly designed to avoidnoise in the emptying of the tank. a

A preferred form of the invention is shown in the drawings, in which Fig. 1 is a sectional side elevation of my improved tank Fig. 2 is a plan view thereof; Y

Fig.3 is an enlarged sect1o V of the discharge or outlet valve, taken along the line 33 in Fig.2

- H in Flg. 3, and

Fig. 4 is a transverse discharge valve casing,

Fig. 5 is an enlarged side elevation of the inlet valve, partlyin section, and looking'in the direction of the arrow 5in Fig. 2.

Referring to the drawings, 1 have shown a tank 10 which may be of any usual conv struction and which may be formed of any suitable material; The tank 10 is provided with an inlet pipe 11 and with a discharge pipe 12. The inlet'pipe llextends downward toward the inner bottom of the tank, as'indicated in Fig. 1, and the extreme lower end of the pipe 11 may be reduced in cross section, as indicated at 13 in Fig. 5. 7

A threaded sleeve 15 is loosely slidable on the downwardly extending portion of the pipe 11 and a cap or head 16 is tightly threaded on the lower end thereof. A chamber 18 is provided in the cap 16, and the lower end portion of the cap is closed by a plug 20 having a packing 21 of leather or other suit-' able material seated in a recess 22 in its upper face. Slots or openings 23 are provided in nal elevation sectional view of the taken along the line rockshaft 30,with portionsofthe' frame eX- tendlng along the sides of the tank and also across the endthereof remote from the rock shaft-30. v

A cylindrical float 33 is provided with a plurality of ears or brackets 34 through whichthe side portions or legs of the frame extend. The legs of theframe 32 preferably converge toward the rock shaft 30, thus preventing displacement of the float toward the rock shaft when the device is'in use. The ears 34 may be additionally secured to the frame 32 by solder or brazing, ifso desired.

The threaded sleeve 15 will'be so adjusted in the collar 25 that when the float 33 is raised by the water to the desired upper water level, the packing21 will be firmly seated against the lower end of the lower portion 13 of the inlet pipe 11. When the water' level in the tank falls, the downward movement of the float will release the upward pressure on the sleeve 15 and the packing 21, permittng these parts to move downward and allowing water to enter the tank through the chamber 18 and slots 23. e

By adjusting the sleeve 15 in the collar 25, the'float level-may bechangedto vary the amountof water used each time the tank is emptied.

My improved .supply valve and the float control therefor is simple and substantial in 7 construction, is easily adjusted, and is eX-' tremely reliable in operation, as the float is firmly attached 'by two arms to the rock shaft 30 and no adjustment of the float or bending of the-frame 32is ever necessary to adjust the water level or tovary the seating of the packing 21 against the lower end of the supply pipe. If the packing 21 becomes worn it may be very readily replaced by unscrewing the plug 20. 1 I

In Figs. 3 and 4 I have shown the details of construction of my improved outlet; or dis charge valve. A valve casingAQ is seated V 2) has the ends thereof firmly secured in thein an opening 41 (Fig. 3) in the bottom of the tank 10. The casing is provided with an outwardly enlarged sleeve-like upper extension 42 which provides a shoulder 43 adapted to be seated againstasuitable packing 44. The lower end of the casing 41 is threaded to receive a clamping nut 45 by which the casing may be secured in position. The discharge pipe -12-may beconnected in any convenient manner to the lower end of the casing 40 as by being threaded into a bushing 46 which in turn is threaded into the lower end of the nut 45 and is seated against the lower end surface of the casing 40.

.The casing 40 is also provided with an upstanding annular flange 48 formng a valve seat, and with a plurality of ports or openings 49 through which water may flow to the discharge pipe 12 when the outlet valve is open. A plunger 50 isguided at its upper end in a bracket or bearing 51 (Fig. 1) mounted on the side of the tank 10. A cup-shaped member 52 is mounted 011 thelower end of the plunger 50 and a suitable packing ring 53 is seated in the member- 52 and is retained in position by a nut 54, threaded on the reduced lowerend of the plunger 50. The member52 is quite loosely slidable in the sleeve portion 42 of the casing 40 and the packing 53 is seated against the upper end of the annular flange 48. The packing 53 may be of leather, rubber or any other suitable packing material. 7 r

A coil spring 55 on the plunger 50 engages the bearing 51 at its upper end, and at its lower end enages a collar 56 secured on the V plunger 50.. The spring 55 acts to depress the plunger 50 and to hold the packing 53 normallyseated against the annular flange 48. The upper end of the plunger 50 is slotted to receive the end of an actuating lever 60,

pivoted at 61 to an arm 62 secured tothe bracket 51. The lever has a pin and slot connection with the plunger 50 and may be actuated by the usual pull chain 63 or in any other-convenient manner. When the chain is pulled, the plunger 50 is raised, permitting water to enter the sleeve 42 through the ports 49 and to escape downward through the discharge casing 40 and discharge pipe 12.

. I have made s ecial provision for silencing the water as it OWs downward through the outlet valve. For this purpose I provide a transverse partition (Fig. 3) extending across the discharge casing 40 from one side to the other thereof and having its upper end ortion slotted to provide a series of tongues 2, which are bent alternately in opposite directions, as clearly shown in Fig. 4.

In actual operation it has been found that the provision of the partition 70 with the oppositely disposed upward extensions or tongues 72 breaks up the flow of water through the discharge casing 40 in such manner that the usual whirlpool or suction effect ing motion of the water. 7

service without repairs or replacements. If

it is desired to replace the packing 53, this may be readilydone by removing the plunger 50 and loosening the nut 54.

All parts of the mechanism may be easily and quickly assembled or removed, reducing the cost of repairs. I

Having thus described my invention and the advantages thereof, I' do notwish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is i 1.. In a flush tank, an outlet valve having a discharge passage, and a partition member mounted in said passage and extending diametrically across said passage and lengthwise in the line of flow, said partition memeigs nating noise when the tank is' emptied-1100 through said valve by obstructing'the whirl- 2.

tank is emptied through said valve.

3. In a'flush tank, acasing, a discharge valve comprising a tubular valve casing secured in the bottom of said tank, valve means to control the flow of liquid through said case:

said valve is substantially eliminated. w

said partition member having ofl'set lugs alternately arranged along the edge of said partition, and said partition extending crosswise of said-discharge passage member and ofiset lugs substantially eliminatingnoise when the tank is emptied through said valve by obstructing the whirling motion of the water.

5. In a. flush tank, an outlet valve havin a discharge passage, and a partition mem r mounted to extend diametrically across said passage and lengthwise in the line of flow, said partition member having ofiset lugs angularly disposed along one edge of said partition and at an angle of substantially sixty degrees to each other, and said partition member and offset lugs substantially eliminating noise when the tank is emptied through said valve.

In testimony whereof I have hereunto affixed my signature.
